Problems solved by technology

The toe of the rocky slope moves forward against the inner retaining wall of the road, encroaching on the road surface year by year, and in severe cases, completely blocks the road and interrupts traffic. Passing vehicles are frequently hit by rolling boulders, resulting in tragic car crashes

Embodiment 1

[0046] Embodiment 1: as Figure 1~7 As shown, a rock slide protection system includes a screening rock slide prevention system, a speed reduction buffer system, and an anti-seismic impact system that are sequentially arranged on the slope surface 1 of the slide rock slope. Above the buffer system, the anti-shock and anti-shock system is fixedly installed below the deceleration buffer system. The screening anti-slide system includes a 4-stage screening anti-slide device. The screening and anti-slide device includes a protective screen frame 5 and a column 10. , the inner side of the column 10 is vertically provided with a chute 13, the column 10 is fixedly arranged on the rock slope slope 1, the protective screen frame 5 is slid in the chute 13 of the column 10, and the deceleration buffer system is a deceleration buffer step 2. There are clearing access roads 20 on both sides of the deceleration buffer steps, and the cleaning access roads 20 are connected to the highway 3;

Abstract

The invention relates to a gravel sliding slope protection system and method, and belongs to the technical field of geological disaster prevention and control. The gravel sliding slope protection system comprises a sliding gravel screening anti-stop system, a speed-reduction buffer system and an anti-seismic and impact-prevention system which are sequentially arranged on the slope face of a gravelsliding slope; the sliding gravel screening anti-stop system is fixedly arranged above the speed-reduction buffer system, and the anti-seismic and impact-prevention system is fixedly arranged below the speed-reduction buffer system; the sliding gravel screening anti-stop system comprises sliding gravel screening anti-stop devices of two or more stages; the sliding gravel screening anti-stop devices comprises protection screening net frames and vertical columns, sliding grooves are vertically formed in the inner sides of the vertical columns, and the vertical columns are fixedly arranged on the slope face of the gravel sliding slope; and the protection screening net frames are arranged in the sliding grooves of the vertical columns, the speed-reduction buffer system is a speed-reduction buffer step, and clearing shortcuts are formed in the two sides of the speed-reduction buffer step and communicate with a highway. Various large, medium and small gravel sliding slope disasters can be subjected to systematic pre-protection, the gravel sliding slope disasters are minimized, and the problems such as secondary slope sliding are solved.

Description

technical field [0001] The invention relates to a rock slide protection system and protection method, belonging to the technical field of geological disaster prevention and control. Background technique [0002] The sloping stone slope is a kind of natural colluvial slope developed in a special alpine glacier zone in the northern part of the China-Pakistan Highway. According to the unique particle composition and particle size distribution characteristics of this kind of colluvial fracture, the authors named it Liushipo, which is a typical type of slope geological hazard on the China-Pakistan Highway. [0003] The rocky slope seriously threatens the traffic safety in the northern part of the China-Pakistan Highway, and is a major hidden danger of the highway reconstruction and expansion project. The toe of the rocky slope moves forward against the inner retaining wall of the highway, encroaching on the road surface year by year, completely blocking the highway in severe cas...
